Keeping your DSLR Sensor clean when changing lenses

With a film camera, you effectively have a new sensor every time you take a picture. With a digital camera the same sensor is used for every shot. This is not really a problem with a sealed compact, fixed-lens digital camera. But with single lens reflex cameras (DSLR’s), taking lenses on and off the camera, usually leads to the sensor becoming contaminated. This means it is most important to adopt a ‘dust aware’ approach to your photography.  These can include changing lenses out of ‘Dirty Air’, making sure the back of the lens is dust free before fitting it to the camera and keeping the camera upside when changing lenses.  We do have products available that can make a ‘Clean’ lens changing area if you have no choice but to change the lens in a dusty environment.  Taking these precautions can reduce the need to clean the camera sensor.
